Abstract

Hyperbolic encounters of compact objects are common interactions in dense environments. During this process a significant amount of gravitational radiation is emitted depending on the parameters of the system. Here we give a parametric description of the radial motion valid for general binary orbits and the radiative energy and angular momentum losses for binaries with spinning components.
